【摘要】 用改进的L-P法求解了强非线性Duffing方程和一类非振动型强非线性微分方程的初值问题 ,计算过程简单 ,精度也比张佑启等[2 ] 的改进的L-P法的更好

【Abstract】 In this paper,using the improved L-P method,the a ut hor seeks to solve the initial value problems of the strongly nonlinear Duffing equation and a class of nonoscillation type differential equation.Its calcultati o n process is quite simple and the accuracy of the results of this paper is bette r than that of the improved L-P method proposed by ZHANG Y.Q .
